湖北省巴东县农作物现状普查与分析

Investigation and analysis of crops germplasm resources in Badong county,Hubei province

分析巴东县1956、1981、2014年的主要粮食作物、果树、蔬菜及主要经济作物栽培面积、种植方式及产量等变化情况,发现巴东县区域优势明显,自然资源丰富,主要粮食作物地方品种基本消失,粮食作物种植总面积有所浮动但比例不大,玉米一直是巴东县粮食作物中最重要的作物;果树、蔬菜及主要经济作物种植面积迅速增加。普查中收集到44份地方资源。针对巴东县地方农作物资源丰富、农业基础建设薄弱、自然灾害严重、农业科技含量低,提出了加强现有资源的保护和利用、加快农业新品种的培育和新技术的推广培训、加快现代农业产业化建设,发展地域特色农业等对策。

There are different types of wheat,rice,corn,rape and other crop germplasm resources in this bank.44 local resources were collected in the resource investigation.The changes of cultivated area and yield of main food crops,fruit trees,vegetables and main cash crops in Badong county between 1956,1981 and 2014 were analyzed.It was found that Badong county had obvious regional advantages,was rich in natural resources,and the local varieties of major food crops have nearly disappeared.The total planting area of food crop changed a little in these three investigations,and corn is the most important food crop in Badong all the time.The planting area of fruit trees,vegetables and cash crops increased rapidly during the different periods.According to the abundant resources of Badong county,the weak agricultural infrastructure construction,the severe natural disasters,and the low element of agricultural science and technology,some countermeasures were proposed,such as strengthening the protection and utilization of existing crop resources,accelerating the cultivation of new agricultural varieties and the extension and training of new technologies,accelerating the construction of modern agricultural industrialization,developing agriculture with regional characteristics.
